BACKGROUND—FIELD OF INVENTION

This invention relates to devices and methods for human motion capture.

INTRODUCTION

There are many potential applications for wearable devices such as smart clothing which can enable human motion capture. These potential applications include: athletic training and motion capture for sports which involve extensive lower-body motion (such as bicycling and soccer), extensive arm motion (such as tennis and golf), extensive lower-body motion (such as bicycling and running), extensive spinal motion, extensive forearm motion (such as tennis and golf), wrist motion (such as tennis, golf, and Frisbee), ankle motion (such as running and soccer), finger and hand motion (such as tennis, golf, baseball, and fencing), athletic performance measurement and improvement; and entertainment, gaming, and artistic applications (such as animated pictures, avatar animation, computer animation, computer gaming, dance instruction, dance performance, gaming input devices, graphical animation, motion capture, motion picture animation, motion pictures, movie making, performance arts, training and motion capture for playing musical instruments, virtual gaming, virtual reality); and health, fitness, and medical applications (such as avoidance of repeated motion injuries, biofeedback, biomechanical analysis, caloric expenditure measurement, caloric intake monitoring, cardiac function monitoring, congestive heart failure assessment, energy balance, ergonomic evaluation, fall prevention and detection, gait analysis, medical diagnosis, medical therapy, nutritional monitoring and improvement, orthopedic therapy, orthotic design and fitting, physical therapy, plethysmography, post-operative therapy, posture correction, pronation analysis, pulse monitoring, range of motion assessment, rehabilitation assessment, repetitive stress injury avoidance, respiratory function analysis, spinal injury avoidance, spinal motion assessment, telemedicine, telesurgery, virtual exercise, weight management); and human-computer interface and telecommunication (such as gesture recognition, telerobotics, telesurgery, telepresence, notifications, telecommunication, teleconferencing, telepresence, telerobotics, virtual commerce, and virtual reality interaction).

There are different types of sensors which can be incorporated into smart clothing for human motion capture, but each has limitations in addition to strengths. For example, inertial motion sensors do not require form-fitting clothing to measure motion and can measure relatively small motions, but can suffer from drift and not provide posture identification when first activated. Stretch sensors can help to correct drift and can provide posture identification when first activated, but can be less accurate in loose-fitting clothing and for small motions. There remains a need for accurate and unobtrusive smart clothing which enables ambulatory full-body human motion capture.

SUMMARY OF THE INVENTION

This invention is smart clothing which enables human motion capture through combined analysis of data from dual inertial sensors and dual stretch (or bend) sensors. These different types of motion sensors have complementary strengths and weaknesses. For example, inertial motion sensors do not require form-fitting clothing to measure motion and can measure relatively small motions. However, inertial motion sensors can suffer from drift and lack of posture identification when first activated. Stretch sensors can help to correct drift and can provide posture identification when first activated, but can be less accurate in loose-fitting clothing and for small motions. Combining data from these motion sensor types enables more accurate measurement of human motion through smart clothing.

In an example, this invention can be embodied in smart clothing (e.g. a smart shirt), wherein a portion (e.g. a sleeve) of the clothing has a longitudinal axis which spans a body joint (e.g. an elbow), a first cross-sectional circumference of the portion is proximal relative to the body joint (e.g. around the upper arm), and a second cross-sectional circumference is distal relative to the body joint (e.g. around the lower arm). As used herein, proximal means closer to a person's heart and distal means farther from the person's heart when the person is in Vitruvian Man configuration (made famous by Leonardo da Vinci and also shown in FIG. 1). Also, a first inertial motion sensor (e.g. an accelerometer and gyroscope) is incorporated into the clothing at the first cross-sectional circumference and a second inertial motion sensor is incorporated into the smart clothing at the second cross-sectional circumference. Further, two stretch (or bend) sensors in the smart clothing span the body joint between the first cross-sectional circumference and the second cross-sectional circumference. These stretch sensors collect data concerning transmission of electromagnetic energy through them, which is changed by motion of the body joint. Several examples of stretch sensor configurations are disclosed herein. This invention also includes a data processor which analyzes data from the dual inertial motion sensors and the dual stretch sensors to measure the configuration and/or motion of the body joint.
